My invention 'A relatesV tov envelopes and4 more particularly to combined letter sheets and envelopes. i f Oneobjectof my invention is to provide afletter .sheetithat when folded has the a pearance of an envelope and which can e utilized for'a'reply, without the writing of addressesotherfthan those initially appear-l ing on the sheet. f i L Another object of my invention is to providewan envelope of the so-called outlook type wherein there is means within theenvelope for preventing enclosuresfrom slid# ing. across the windowof the envelope, and thereby obscuring an address intended to be visible through the'iwindow. Y

Another object of my invention is to providev a combined lett-er lsheet and envelope which may Vbe employed. bot-h as a sending and reply envelope, without the necessity Vof the recipient thereof folding Vit along lines other" .than the voriginal lines, in -returning the same to the sender, and vwherein the return address `may,` nevertheless, be made visible through the envelope window.

Still vanother object of `my invention is to provide acombined envelope and letter sheet of generally improved form.

the enclosed drawing, Figure 1 shows the sheet in open condition with the letter face thereof to the front; Fig. 2 is a view showing the rear side of the sheet of Fig. 1; Fig. 3 shows the sheet partially folded; Fig. 4 is a perspective view showing the sheet at a further stage of folding; Fig. 5 is a view, on an enlarged scale, showing the completely folded sheet; Fig. 6 is a view taken on the line VI-VI of Fig. 3; and Fig. .7 is a fragmentary view of a portion of the sheet of Fig. 1.

Figs. 1 and 2 showl the unfolded sheet, Fig. 1 showing the face or letter side of the sheet. This side of the sheet may contain a communication, advertising, andV also an order form. The upper half of the side of the sheet shown in Fig. 2 may be similarlyVV utilized. The numeral 8 indicates the ad dressee, while the numeral 9 is a flap containing the senders name and address. This Y flap is shown as cut from the sheet to proi930. serial m. 455,567;

Videla window 1o therein., which window with adhesive materiahfor'a VpurposeI hereinafter described. y. Y y v When the.v sheet'` hasj@ been printed or written, previous to mailing, the flap `9'1fbeing bent back asshown in Fig.V 1, it is folded completely across `itself'on the line 11a, thus bringing Athe addressees' name in lfrontl of Vthe window 10, as shown in Fig.'3, the sheet then being folded along the line 12,.Jan'd the edge of such narrow folded portion is caused to enter slitsl 13. and 111V in the opposite edgeoffthe sheet.. Those". portionsjof saidl opposite edgexwhich lie 'between the slits 13 and the slits 1i are ldisposed within the fold 112,k so that the rear side of the nar- TOW PJOltOIl 12a, as viewed in 4I `ig.=1wil1 be exposed as vshown `in Fig. 3, `and the senders name and address may be printed on said narrowportionV as indicated at15,

in Figs.y 3', 5 and 6, particularly. {The interlockingefect produced bythe folded portion 12a'eXtending into the-.slits 13 and .14 vserves to prevent gaping yof'gthe folded sheet at its upper edge.l An order blank or other enclosure may be `loosely placediin thesheet giving fit the appearance :shown inf'l'figizifl.

Adhesive material along thel line Y 19 is then moistened so that the flap formed by 'the foldA 18 may be caused'toadherelto the `fold Jos Y of thefflap 17.' A strip 20-isappliedvto 'the rear side of the sheet by adhesive contained on only a lportion of the rear :side lof the strip, as indicated by dotted zlines 20a, (Fig. so that ity can. bereadily -removed` by `.the ad- `dressee. This strip is utilized to receive the the fold lines 17 a'nd18 to effect separation of the adhering portions at 19. He may then write, or Otherwise place, Ahis reply in the .tion stamp. e

sheet yand-refoldit along the original lines, except that the flap 9 containingthe original senders address willf-beffolded down over the window 10. In returning the letter sheet,V

V'fof adhesive upon said infolded portions, and Y the adhesive along. the line 21 is moistened for the purpose of sealing the sheet, and the strip 20 torn ofi' to permit aiiixing of lanother Y postage stamp and to provide aclean surface for the imprint yof the p'ostniasters -eancella- I'claim as my invention z-f i ,1. Al-Combined envelopefand letter sheet consisting of a sheet folded along a line'laterally offset from amedian line of the-sheet, a fold adjacenteto theedge of thelonger portionof the primarily,foldedsheet-and overlapping theopposite edge lof the'shorter folded portion of thesheet, Vthe sheet being again folded across its width, on'a line extending at right angles ,to `the first folded line, and those-edges of the sheetparallel to the last named fold line being'inturned and united byV astrip of-adhesivel applied :adjacent to one of thesecond-namededges, the sheet being p'rovidedwith a second strip of adhesive parallel to-but spaced'a. slight distance ,from the first-named strip Vof adhesive.k

2. A combined envelope and letter sheet comprising asheet of paper .folded upon it self,means for securing together those'edges of thesh'e'et which are brought into proximity to one another nby vthe'folding operation, the sheet folded as-aforesaid being again :folded upon itself, and having'the edges thereof i' whieh'arebrought into proximityl to one 'another by the second-named folding operastionfturned inwardly, and means vcomprising two-:spaced lines kof adhesive upon one of saidinfolded portions for securing the infoldedportions together. e,

3. combined envelope and letter sheet consisting of a sheet having continuous man ginal edges and being folded along aline Y laterally voffset'from a median line of the sheet, a foldy adjacent to thel edge of the longer'portion of the primarily folded sheet to receive the opposite edge of the shorter folded portion of the sheet, the sheet being again folded across its width, on a line `extending at right angles to the first folded line, and those edges ofthe sheet parallel to the last-named fold line being inturned and united, and a flap `outl partially away from one portion of the sheet, the said flap con- .A

taining an address yonits outer side and being foldable back against the face ofthe sheet i to expose an address contained on said sheet,

the sheet thus folded'forming an envelope being again'folded upon itself .and having Y the-edges Vthereof `which z are brought into proximity to lone another lby the seconde,

nained folding operation turned inwardly,

havingall its edges closed, two spaced lines lan integral ap formed from a portion of said sheet at the side of the envelope and thesheet thus-'folded vforming an envelope folded over theother saidedge, the folded j V sheet being lagain-,foldedl uponfitself and having the edges .thereof which are brought into proximity to one another by the second# namedl folding operation turned inwardly, the sheet thus folded forming. anl envelope having all its edges closed, two space'dzlines of adhesive upon said infolded portions, and an integral flap formed Vfrom a'portion of said sheet at the side ofthe envelopeY and beingfoldable back against therface of the sheet to expose an addresscontained thereon, said envelope being sealed for useby, means of onel of said lines of adhesivel and being adapted-to be resealed by the'othersaid line l of adhesive.
